for all dates and rights vincident to the filing thereof and the filingof foreign applications vcerrespondiing thereto.

This invention refers to book-keeping and accounting machines and thelike and involves a new principle of e'ecting the control of balancingtotalizers by their operating means. 'I'he invention has for itsprincipal object the provision of a machine for maintaining an accountof a pluralityof related factors. For this c., New York, N.

November 30, 1937, Serial In Sweden June 7, 1928 ents, to Ekonomireg-Y., a corporation of purpose the machine comprises a plurality bf'adding and subtracting totalizers and operating means loperable both toselect rality of said totalizers for actuation and simultanedusly toselect the sense in which 'each of said totalizers shall be actuated.

Another object of the invention is to provide a machine of the kinddescribed comprising means for setting the totalizers way that thetotalizers which in a certain case are to be combined for some purposein one and the same operation of the machine, are directed, ln allrespects, from one single operating means covering the whole operation,so that, for each cycle of the machine, one operating means only has tobe manipulated once, besides the depressing of the numeral keys.`

Another object of the present invention in itsl preferred embodiment ismore particularly to provide a machine for financial control,bookbalancing and book-keeping, based on an improved accounting method.

According to this method every commercial enterprise or businessactivity mustcomprise, financially, four fundamental factors, viz.assets, liabilities, profits and losses. 'Ihe different classes,into-which the/ assets are divided, e. g. cash, stock, sundry debtors,etc. as well as the different classes of liabilities, profits and losseswill be called special factors. 1

Business activity consists of a series of individual transactions whichin fact always involve changes in the amounts of the said factors of theenterprise. implies a simultaneous change (increase or decrease) of thesame size in the amounts of two special factors, a fact which in thedouble entry book-keeping appears in such a way that every debit entryhas its corresponding credit entry,

further a plufor actuation in such The individual transaction always andvice versa. With logical necessity these changes in two special factorscannot occur in more than the eight following ways. (Designations 'used:T for assets, S for liabilities, V for profits, F for losses.) f

l. A kind of loss increases (F+) whilst at the same time a kind ofassets decreases (T); 2. A kind of loss increases (F+), whilst at thesame time a kind of liabilities increases (S+):

3. A kind of assets increases (T-l-), Whilst at the same time a kind ofprofit increases (V+) 4. A kind of liabilities decreases (S), whilst atthe same `time a kind oi prent increases (V+) 5. A kind of assetsincreases (T+), whilst at the same time another kind of assets decreases(T-) 6. A kind of assets increasesiT-l-l, whilst at the same time a kindof liabilities increases (S+):

7. A kind of liabilities decreases` (S), whilstv at the same timeincreases (S+) s 8. A kind of liabilities decreases (S1), whilst at thesame time 'a (T-);

The above outlined method involves (l) the analysis of the transactionto be recorded, according to one of the store-mentioned eightcombinations of the four fundamental accounts: assets, liabilities,profits and losses; (2) and also another kind of liabilities therecording of the transaction in question simultaneously four times, viz.in the debit of one account, in the credit of another account, on thevoucher and in the day-list. To carry out this method the machineaccording to the invention is provided in this particular case with aplurality of totalizers operable 'for addition and subtraction, interalia corresponding to the fundamental factors: assets, liabilities,profits and losses, and further provided with operating means to set inoperative position simultaneously, in the right sense, those two of saidtotalizers that, according to the analysis, are to be affected by thebusiness transaction to be recorded. Further the machine must be soconstructed that in one single operation it immediately shows intotalizers the amount of the net profit or net loss and also the amountsof the assets, liabilities, profits and losses and the total sum of theamounts of the transactions registered.

Anotherobject of the present invention is to provide a machine, thefunctioning of which is based on aforesaid method, by means of whichmachine the number of the economic analysis of the voucher according tosaid method, the date,

kind of assets decreases the controlling number and the amount of thevoucher and other items can be printed simultaneously a, plurality oftimes, for instance in the debit of one account, in the credit ofanother account, on the voucher and in the journal-list, thus permittinga direct book-keeping up to 100%.

Another object ofthe present invention is to provide a machine ofthekind described, in which the said operating means for simultaneouslysetting the totalizers into working position, consists of one or moreso-called analysing keys. Ii only one analysing key is used, said keyshould be adapted to be set in different positions so as to both selecta plurality of totalizers for actuation and, simultaneously, select thesense, in which each of the totalizers thus selected shall be actuated.Preferably, however, the number of analysing keys is equal to the numberof totalizer combinations, i. e. for the embodiment shown as many as theclasses of transactions, i. e. eight. It is further possible that thesaid operating means consists oi electromagnets instead of keys, andperforated cards and brushes may also be utilized as operating means, inwhich either the cards or the brushes are movable re1- ative to theother members.

The machine may be provided with one or more adding totalizers, one oiwhich, the so-called chronological total amount totalizer, indicates thesum of all items recorded. Further the machine may be provided with aprinting device printing automatically, that is to say'without themedium of any key,-the number of the litems in chronological orderwhich, of course, facilitates the control.

Further the machine may be provided with operating means to restore themachine in any desired position. if an item has been erroneouslyrecorded and printed the totalizers can by the said operating means berestored to the positions which they assumed, before the erroneous itemwas set up and printed. This restoring means may consist of a singlekey, especially when the analysing means consist of one key only, but,preferably, it comprises a row of keys adapted to set the totalizers tocarry out the calculation in opposite sense to that for which thecorresponding analysing keys would set said totalizer.

The present invention will now be described in detail with reference tothe accompanying Fig. 8 is a section on the line VIII- VIII in F18. '1.

First the principle oi my new accounting method will be described in oneexample with drawings which show a preferred embodiment of a machineaccording to the invention.

In the drawings:

reference to Fig. l. In this figure, i, 2, 3, 4, 5, l, 'L and ldesignate eight analysing keys correspending each to one of the eightbusiness transactions as indicated to the left of the keys in accordancewith the designation above referred to. l titled?,

designate eight restoring keys corresponding each to the businesstransactions opposite io that of the corresponding analysing key asindicated to the right of said restoring keys. That is to say, key

for instance, represents the business transaction T-i,-F because key irepresents the business transaction F+T and so on. Between the two rowsof keys there are shown six totalizers representing in order from aboveand downwards the assets totalizer RA', the liabilities totaiizer RB',the chronological total amount totalizer TR, the balance totalizer RC',the proiit totaiizer RB" and. the loss totalizer RA". The manner inwhich the different analysing and restoring keys select said totalizersfor actuation and simultaneously select the sense in which each of saidselected totalizers shall be actuated is illustrated by way of linesdrawn from the keys to the totalizers. Thus it is seen, for instance,that the analysing key i representing the business transaction: increaseoi loss and decrease of assets, that is F+T-, selects the assetstotalizer RA', the loss totalizer RA" and the balance totalizer RC', andsimultaneously determines subtraction for RA', addition for R andsubtraction tor RC'.

Further this key. as well asall other analysing keys, selects thechronological total amount totalizer 'IR adding all items in succession.It is of course understood that there may be more than only one suchadding totalizer TR. The

restoring key y selects the assets totalizer RA', the balance totalizerRC', the loss totalizer RA" and the chronological total amount totalizerTR and simultaneously determines addition for 'RA'l and for RC' andsubtraction for RA" in accordance with the business transactionrepresented by said key. In other AWords the analysing key I and therestoring key fi 7 XandX are only connected with the chronological totalamount totalizer TR, said keys representing business transactions whichonly cause a transfer in the assets and the liabilities accounts,-respectively. In Fig. l, said keys are shown by dotted lines to beconnected with the plus side and the minus side of the assets totalizerRA and the `plus side and the minus side of the liabilities'to= talizerRB', respectively, as a depression of said keys will influencecorresponding printing devices without influencing the correspondingtotalizers.

The general arrangement of the machine The embodiment of the machineillustrated in the drawings comprises (see especially Fig. 2) twosimilar machine sections A and B placed on each side of a third machinesection C. The three machine sections A, B and C comprises each twoadding and subtracting totalizers. For the sake of clearness thetotalizers of the central sectionv C only are shown in Fig. 2 and aredesignated RC', RC", respectively, but as also the other totalizers willbe referred to in the fol-lowing specification, they will be termed RA',RA" and RB', RB" belonging to the machine sections A and B,respectively. According to Fig. 3 the machine section A is shown tocomprise also a chronological total amount totalizer TR. Each machinesection comprises further a printing device TA, TB, and TC,respectively, with appurtenant hammer mechanism SA, SB and SC,respectively. The three machine sections A, B and C are controlled by acommon key-board D.

The key-board The key-board D comprises in the embodiment shown severalrows of keys, viz. reckoned from the left in Fig. 2 one series E ofeight keys I to 8 inclusive for selecting the totalizers and `theirsense of calculation and corresponding to the analysing keys I to; I inFig. 1, one series F ot eight keys 8 xto X inclusive, corresponding tothe restoring keys I 8 X to X in Fig. 1, one series G of twelve keys forrecording the name of the month and designated by the ilrst threeletters of the month, the keys corresponding to the months January toSeptember being arranged in the third key row and the keys correspondingto the months OctoberA to December in the fourth key row, one series Hof three .keys and one series K of nine keys for recording the day ofthe month and designated by I, 2,

3 and I to 9, respectively, and at last a plurality of rows of numeralkeys proper, as a whole designated L, in the embodiment shown five rows.

Further the rst key row contains an additional key marked K+, the secondkey row an additional key marked K and the fourth key row an additionalkey marked L1. The function of these additional keys will be explainedlater. lit should be observed that also other keys may be providedfulfilling different objects.

The transfer system from the key-board to the selector comprises a plateI6 pivotally mounted at its opposite ends at 'I8 on a key-board`vpartition I9. A spring 2B tends to hold said plate I6 in such positionthat its fore end is right before a downward projection 2| on theactuator rod I4, the distance between saidprojection 2I and the fore endof the plate I 6 corresponding to one tooth for the purpose to beVdescribed later on. The key rods I0 are eachprovided with a projection22, and a spring 23 connects said projection with another key-boardpartition 24. The actuator rod I4 is at its fore end provided with aprojection 25. In Figs. 7 and 8 one key is illustrated in its depressedposition and, as shown, the projection 22 on the corresponding key rodI0 forms in said position a stop for the actuator rod- I4 in a manner tobe'described later on.

During the setting operation a depressed key in each of the rows G, H, Kand L is held in its depressed position by a locking bar I5 extendingalong the key row and provided with a pin II for each key rod I0, saidvpins I1 co-operating with shoulders 21 on the key rods I0. A spring 29'tends to move the bar I5 backwards, that is to say to the left in Fig.7. Any depressed key Y is returned to starting position by a 'restoringof an arm secured to the rocking main shaft |00, the lever 68 being atthis end provided with an inclined surface 12. the lever 68 is providedwith an. elongated slot T4 mounted to slide and to rock on a stud 13secured to the machine frame. A spring 10 tends to rock the lever 63 incounter-clockwise direction (Fig. 3).

The actuator rods I4 are each actuated by. a spring 26 (see Fig. 3)secured at its one end at 28 to the rod I4 and at its other end at 30 tothe machine frame. The springs 26 tend to move the actuator rodsbackwards (to the left in Fig. 3). At their rear ends the actuator rodsI4 are each pivotally connected at 32 to a toothed gear or actuatorwheel 34. The gears 34 are all loosely journalled on a common shaft 36mounted in any suitable manner in side walls 31 and 39 of the machineframe, see Fig. 2. These toothed gears 34 form the actuator of themachine and will be more fully described later.

in the embodiment shown, the third row, reckoned from the left in Fig.2, comprises, as stated above, nine keys marked Jan to Sep and thefourth key row contains the remaining month keys Oct, Nov, and Dec."These month keys in the fourth key row are coupled tothe third key rowand operate the actuator rod l of said key row which, consequently, mayassume twelve different positions, the arrangement above described beingchosen for the sake of symmetry.

The transfer system for the analysing keys and the restoring keysdiffers somewhat from that for the other keys. The key rows E and F havea common actuator rod which i'or the sake of convenience is alsodesignated i4. The keys consist each of a key-rod 40 (see Figs. 3, 9 and1C) having a key-tab 42 and abutting each with its lower end against oneend oi' an angular catch 44 fulcrumed at 46 in the key-board frame inany suitable manner. A spring 48 tends to maintain the key in raisedposition. The catch 44 engages normally a releasing bar 50 holding saidbar in lowered position against the action of a spring 52. The bar 50 isprovided with three abutments 54, 56 and 50 in the order from above' anddownwards. Arranged above/the uppermost row of abutments 54 is arestoring plate 60 normally out oi' engagement with said abutments 5ft.One edge E2 of the plate 50 forms a shaft suitably journalled in theframe at Si and $3 and serving as swinging axle for the plate. Pivotallyconnected to said plate 60 at one end on the edge opposite to the shaftB2 is a link 64 extending downwards and provided at its lower end withan eye 56. Projecting into said eye 66 is the one end of lever 68 Flg.3).

Arranged above the second row of abutments 5B on the releasing bars 50(see Figs. 3 and 9) is a stop bar pivotally mounted in the machine frameat 82.- ln its normal position this stop bar 80 prevents any backwardmovement of the actuator rod i4 from the starting position thereof, theabutment 84 on said selector rod I4 cooperating with some play with saidstop bar 80. The actuator rod i4 is arranged between the second abutmentrow 56 and the third abutlment row 58 and is pivotally connected, in thesame manner as other actuator rods i4, at its rear end at 32 to one ofthe actuator wheels 34 of the selector.

Extending below the key-board D (see Figs. 3 and 10) are two rows ofshafts each comprising eight shafts and 92, respectively. JournalledIntermediate its ends l are each connected with one arm of the bellcranklever 98 by means of a similar wire 58. In order to permit transmissionfrom the keyboard to the three machine sections, the shafts 90 and 92extend laterally of the keyboard at both sides thereof, and for eachsection there lare provided similar bell-crank levers 34 and 96,

preferably at both sides of the unit, as is shown in Fig. 2. Arrangedbelow the actuator wheels 34 of each machine section and at both sidesthereof is a pair of bell-crank levers 102 and |04 pivotally journalledin the machine frame about spindles H0 and H2, respectively. Wires |06connect one arm oi each of the bell-cranks $4 and 96 with one arm ofeither a plus lever 104 or a minus lever I02'or both of the varioustotalizers in the three machine sections A, B and C in accordance withthe business transactions represented by the corresponding analysing orrestoring key (see Fig. 1l). The other arms of said bell-cranks areconnected to levers or bell cranks to control the setting of the varioustotalizers in a manner to be described later.

When one analysing key only is used, which is adapted to be set indifferent positions, it may be carried out in practice as shown forinstance in Figs. i9, 20 and 2l or Figs. 22, 23 and 24. In thefirst-named case an arm 30l is ilxed to a shaft 300 plvotally mounted inthe frame of the machine. The upper end of the arm. 30! supports bymeans of a pin 302 a lever 303 having a knob 303a for handling the same.This lever is integral with two lateral arms 305 and 30E and the shaftproper 303 is made to slide in a slot 320 in the key board plate 32|.The slot has branch slots 322 and 322x (see Fig. 2l) extending towardseach of the numerals i to 3 and l il X to X respectively, in accordancewith the scheme shown in Fig. l. The arm 301 has a bore hole containinga spring 323 which presses a ball 304 against the lever 303 in one ofthree recesses on the underneath side thereof, in order to retain thelever in one of three positions, viz. either in the central position inthe slot 320 or at the into the slot 322 belonging to the analysing key6 or into the slot 322x: belonging to the analysing key is swung to theleft in Figs. 20 and 2l, the arm 305 will actuate the catch 44 (Fig.19), which releases the bar 50 by means of the spring 52, as describedabove, and the totalizers belonging to a business transaction of thekind 8 (T4-S+) are set. When the lever is swung to the right,

operating with brushes, in which case either 'the` card or the brushesare moved `relative to the other member. The said electro-magnets 3||are mounted in any suitable manner, for lnstance by means of brackets326, on a partition 321 oi' the machine frame. Each magnet has anarmature 3|0 pivotally mounted by means of a pin 3|2 on the bracket 325.The free end of the armature takes the place of the catches 44 of Figs.3, 10 and 19, that is to say it normally rests on the top of thereleasing bar 50. A spring 329 tends to hold the armature in saidposition. The use of electromagnets brings about the advantage that thecontact device or devices for energising the coils of the magnets 3||may be situated, ii' desired, at a distance of the machine proper, andfurther other machines, apparatus or mechanisms which may be requiredfor book-balancing or other accounting purposes could be inserted in thecircuits connecting the contact devices with the electromagnets 3| I. Itis obvious that when :energizing the coil 3| the armature 3|0 isattracted, thereby releasing the bar 50 in the manner described aboveand required for setting the totalizers under consideration. The contactdevices may be carried out in any suitable manner, those shown in Figs.23 and 24 consisting of pairs of contact springs 333, 33| and 332, 333.Each pair oi' contacts may be closed by a lever 303 similar to thatshown in Fig. 20 and pivotally mounted on a swingable arm 30|, or theclosure may be eected by individual keys. The closure ci the vvariouscircuits may, as stated above, also be eiected by means of perforatedcards and brushes. -In the example shown the contact springs 330and 332are insulated by means of blocks 33E and 331.

respectively, from the contact springs 33| and 333. All contacts 33| and333 are by wires 341 electrically connected with each other and with onepole of a source of power, for instance the battery 333. Each of thecontact springs 330 is connected by means of a wire 333 with one end cithe coil oi the pertaining electromagnet corresponding to the analysingkeys to 3, `while the contact springs 332 are connected with theelectromagnets' corresponding to the restoring keys l 3 Xto x The otherend of the coil of the electromagnet 3M is connected by a wire 34| andvia a contact device 343 to the opposite pole oi' said battery 339. Thecontact device 343 is adapted to be closed by a motor or starting key34e which is purely diagrammatically shown in Fig. 23. The operation isas follows: At first the arm 30| is swung in position opposite to one ofthe contact devices 330, 33| or 333, 332, thereafter the lever 303 isturned, whereby the contact springs make contact, and finally the motorkey 345 is depressed. By this means the pertaining electromagnet 3|| isenergised and the bar 30 is released. whereby the totalizers in questionare prepared for actuation.

The actuator Asv already mentioned, the actuator comprises a series ofactuator wheels 34 loosely journalled on a common shaft 36 and eachactuated by a spring |32 tending to rotate the wheel in clockwisedirection as seen in Fig. 3. In the embodiment shown. each machinesection comprises twelve such actuator wheels 34, viz. reckoned from theright in Fig. 2 first five wheels corresponding to the five rowsofnumeral keys L. one wheel for each of the fifth row K, fourth row H andthird row G, one wheel common to the second and first key rows lF and Eand finally three wheels belonging to a device for chronologicalnumeration to be described later on. The shaft 36 extends transverselythrough the whole machine and, consequently, it is not only common tothe actuator wheels 34 of one section but to the actuator wheels of allthree sections A, B and C. These wheels are each in engagement withpinions ||4a, ||4b and ||4c, respectively, (Figs. 2 and 3) and the threepinions engaging corresponding actuator wheels 34 in the three sectionsA, B and C are secured to a common shaft ||6 suitably journalled in themachine frame. In Fig. 2 only one of these shafts is shown in order tomake the drawing clearer.

As shown in Fig. 2, the actuator wheels 34 of the central section C onlyare connected with the key-board by means of the actuator rods I4 or arecontrolled by the device for numeration in chronological order, but asthe said wheels 34 in' the central section C are each positivelyconnected with corresponding wheels in the two lateral sections A and Bby means of the pinions ll4a., ||4b, ||4c etc. and the shafts IIE, allthree machine sections will, consequently, be set in uniform manner inaccordance with the setting on the key-board D. As the varioustotalizers are normally, that is to say at the setting operation, keptout of engagement with the actuator Wheels 34, said totalizers will not,of course, be set in the same manner in all three sections but only theactuator wheels of said sections.

The toothed wheels 34 are in permanent engagement with two upper groupsof transmission gears |30 each group loosely journaled on a common shaft|13 (see Figs. 3 and lil).4 Further the actuator wheels 34 of section Awhich correspond to the numeral key rods L are in permanent engagementwith another lower group of transmission wheels |30 loosely mounted on asimilar shaft |13. An adding and subtracting totalizer is provided aboveeach of said upper groups of transmission gears and in section A a.chronological total amount totalizer TR is provided at the side of saidlower transmission gears |30.

Secured to the actuator shaft 36 are pairs of arms |34 for each section,the free ends of which are connected by rods |36 extending each throughone section and resting normally against one of the spokes |31 of theactuator wheels 34 thus serving as stop rods for said wheels holdingthem in starting position. Pivoted tc one of said rods |36 is aconnecting rod |38, the other endof which is movably connected with acrank |40 loosely mounted on the main driving shaft |00. Secured to saidshaft |00 is an arm |42 provided with a pin '|44 which is adapted toengage said crank |40, when the shaft' is rocked in clockwise direction.s A spring |46 tends to gears it?, catch lsst l:arranged below thetotalizer and journalier" The IThe adding and subtracting totalisers arranged above the upper groups oi transmission gears itil (see Fiss. 3and lo) comprise each series of digit disks loll carrying digits irons l.9. The digit disks itil are each rigidly connected with a toothed gear(adding gear) |52, an the digit dislts loll and said sears are loosemounted on a common spindle loll. *lhs L .s lbl are each in permanentengagement with another gear itil (subtracting gear) loosely mounted ona spindle lill The spindles flrl e loll are journalled at their ends inbridge pi already mentioned section A contains chronological totalamount tctalizer TR (see 2l and 10) comprising a plurality of digit `dlle 265 loosely mounted on spindle 26d and each rigidly connected with atoothed gear 268 adapted to v{zo-operate with the 'transmission gearslll@ oi said totalizer in permanent engagement with the actuator wheelsBil oi this section correspending to the numeral key rows. The spinelle261i is fixed in bridge pieces 2lb loosely journalled on a shaft 2li?mounted in the machine frame.

All 'totalizers are normally held out ol engagement with the respectivetransmission gears i3d as will be described later on.

The control of the totalieers from the lacy-boord The various adding andsubtracting totalizers are set for addition or subtraction by means cithe analysing and restoring keys (lll and f') inv accordance with thebusiness transaction to be recorded. As all these totalizers RA', RA,RB', RB", RC and RC" are controlled by the bellcrank levers lili andHill in the same manner, it will be sufcient to describe the controllingmeans for one pair of said totalizera say RA' and R.

The plus lever it (see Figs. 3 and lll) of the totalizer RA" isconnected by means of a wire lll with onearrn o a bell-crank catch lever56d the machine frame at said lever lli@ b engagement with the corrc235i, end of rnlar support tote' i engagement with c.

Normally engaging said pawl is a double-armed lever lH looselyjournalled on a shaft llo mounted in the machine frame and common to allmachine sections (see Fig. 2) A spring |18 tends to rotate said lever|14 in counterclockwise direction. At its upper end the lever |151carries the abovementioned bridge piece |66 in which the totallzer RA'is mounted. Since the shafts |56 terminate in the bridge pieces Hill, itwill be seen that the selection for subtraction also selects a totalizerforoperation, the wheels being moved into engagement with the actuatorslil') when bell cranlr.

Engaging said segment 232 is4 toothedwheel 34. Secured to vthis segment 234` is an angularly shaped arm 238pivotally connected atl its free end by means of a link 240 to aprojection 242 on a type carrier 244 provided at its upper end withtypes 246 in the form of small pins extending through and beyond thetypecarrier 244 at'both sides theerof. At their one end the pins 246 carrynumerals from 0 to 9 in the order from above and downwards except thepins of the type carrier corresponding to the month keys which carrydesignations from Jan to Dec and the pins of the type carriercorresponding to the fourth key row, which carry only the numerals 1, 2and 3.

The fore ends of the type pins 246 and 250 are adapted to co-operatewith a hammer mechanism designated in Figs. 2 and 3 by SA, SB, SC andSD, respectively. As all these hammer mechanisms are identical andcontrolled by the main drivingshaft in the same manner, it will besufficient to describe one mechanism, for instance SC, reference beinghad to Fig. 3 and especially to Fig. 14.

The hammer mechanism comprises hammers 350 journalled on a shaft 35|.The hub of each hammer has an arm 352 and a projection 353 arrangeddiametrically to each other. Arm 352 is actuated by a spring 354 tendingto move the hammer 350 in counter-clockwise direction. Further thehammer 350 is provided with a pin 355 cooperating with a pawl 356, allsaid pawls being fixed to a common locking bar 351 which is rotatablymounted on a shaft 358 and to which the springs 354 are secured.Connected with the able on a stud 310 and adapted to be actuated androtated in clockwise direction by a roller 31| .on an arm 312 fixed tothe main driving shaft |00 (see Fig. 3).

Levers 313, one for each type carrier 244, are rotatably mounted on ashaft 314 and have their one arm 315 formed as a hook 316 which instarting position of the type carrier is right in front of a recess 311in the carrier, whereas the other arm 318 of the lever 313 is actuatedby a spring 319 tending to rock the lever in clockwise direction. Theupper lend of arm 318 is adapted to be rocked below the projection 353in order to lock the corresponding hammer 350. All the printing devicesare controlled by one and the same operating means 369, 312, the links364 of the hammer mechanisms SA and SB of the two lateral printingdevices TA and TB being by arms 380 connected to a shaft; 383 mounted inthe machine frame, said arms 380 being by links 38| pivoted to the stud392 on the operating lever 369. The platens of the printing mechanismsof the left hand and right hand sections are shown in Fig. 3 anddesignated PA and PC, respectively. i

An additional printing device is provided, by means of which the itemrecorded can be regis'- tered on the day-list on which the items areprinted in chronological order without respect to the mode ofcalculation.' This printing device TD is diagrammatically shown in Fig.3 and consists of type pins 250 arranged in the lower part of the typecarriers 244 in the same manner as in the printing device TA. Theprinting is performed on a paper on the platen PD, the paper being Woundfrom a roll 252 onto a roll 254.

The device for chronological numeration As stated above, the actuator ofeach machine section contains a plurality of actuator wheels 34belonging to a device for chronological numeration. ln the embodimentshown these wheels are the three first ones reckoned from the left inFig. 2. These wheels 34 engage each a pinion 256 (see Fig. 3) looselyjournalled on a common shaft 258. Secured to each of the pinions 256 isa larger gear 260. The actuator wheels 34 associated with this device donot, of course, co-operate with any totalizer wheels but each with aprinting unit. The gear wheels 200 and ten transfer gears 26| engagingsame as well as the pinions 256 form together a counter which is fed onestep for each recorded business transaction. The counter may be of thewellknown Veeder type but in the drawings a counter is shown of the typedescribed in my co-pending application for Letters Patent led onSeptember 25th, 1937, Serial No. 165,775 which application is referredto with regard to the structure and operation of the counter. For thesake of explanation of the operation of the counter in combination withthe machine according to this invention it should only be mentioned thatthe means for stepwisely advancing the counter comprises a lockingmember in the form of a catch 385 adapted to set said feeding means outof function as will be explained later.

The mode of operation of the machine In order to explain the mode ofoperation of the machine it is assumed that of the two totalizers of theleft hand section the totalizer RA'- records assets and the totalizerRA" 1oss, that of the two totalizers of the right hand section thetotalizer RB' records liabilities and the totalizer R profit and thatthe rear totalizer RC of the central section records thebalance. It isfurther assumed that the business transaction to be recorded is thefollowing:

On the 6th May note-paper is bought in cash for $7.25. The cashieranalysesY this business transaction correctly to be of the rst class(F-1-T-, Fig. 1) and writes a number l on the voucher. When the operatorof the machine gets the voucher in his hand and has to record thebusiness transaction, he depresses the following keys reckoned from theleft in Fig. 2: in the rst row E the key I, in Athe third row F the keyMay, in the fifth row K the key 6, in the eighth row the key 1, in theninth row the key 2 and in the tenth row the key 5.

On depressing the key I in the first row E which key is connected withthe minus lever |02 of the rear totalizer RA' (assets=T-) of the lefthand section A, the plus lever |04 of the fore totalizer RA" (loss=F-l)of the same section, with the minus lever |02 of the balance totalizerRC and with the bell-crank |64a pertaining to the total amount totalizerTR in accordance with the diagram shown in Fig. 1, the catch 44 releasesthe bar 50 which moves upwards under the action of the spring 52 wherebyon the one hand the abutment 56 on said bar swings the stop bar 80`outof engagement with the projection 84 of the actuator rod |4 and on theother hand the abutment 58 forms a stop for the actuator rod |4 on thefollowing backward movement of same. The actuator rod I4 cannot yet movebackwards being prevented therefrom by its connection with thecorresponding actuator wheel 34 which in turn is locked by the stop rod|36. When the bar moves upwards, the corresponding bell-crank levers 94and 96 are turnedl in counter-clockwise direction as seen in Figs. 3 and10 causing the levers |02 and |04 to turn in the same direction. Theturning of the minus levers |02 of the rear totalizer RA of the lefthand section A and the rear totalizer RC of the central section Cresults in the pawls |10 releasing the double-armed levers |14 which arenow free to swing in counter-clockwise direction under the action of thesprings |18. This swinging is, however, prevented by the engagement ofsaid levers |14 with the pin 230 on the arm 228. By the turning of theplus lever |04 of the fore totalizer RA" of the left hand section A. thesupporting bellcrank lever |64 of said totalizer will be swung inclockwise direction out of engagement with the end of the spindle |54,this totalizer being, however, still supported by the bridge piece |60resting with its extension 2|2 on one arm of the bell crank lever 208.When the bell-crank 94 is rocked, the bell-crank |64a resting againstthe spindle 264 of the totalizer TR will also be rocked leaving thebridge pieces 210 of the totalizer TR free to move to the right (Fig.3). This movement, however, is still prevented by the sector 215 bearingon the sector 21|. When later the bell-crank 204 is rocked in clockwisedirection, the link 216 and thus the arm 214 will be lifted, so that/thespring 211 can draw the wheels of the totalizer TR into engagement withthe transmission gears |30.

On depressing the key May the corresponding key-rod |0 (see Figs. '7 and8) moves downwards releasing the corresponding actuator rod |4 fromengagement with the locking plate |6 and forming with its lug 22 a stopfor the following backward movement of the actuator rod I4. In the samemanner the depression of the keys 6, 7, 2 and 5 will release thecorresponding actuator rods |4, the different keyrods I0 forming stopsfor said rods |4l on the following backward movement thereof. For thesame reason, as stated above with regard to the analysing key actuatorrod |4, these rods cannot move backward, before the main shaft |00 isactuated. The machine is now set for the record in question.

Before actuating the main shaft, the voucher and two account cards areinserted in the printing devices TC, TA and TB, respectively, theaccount cards being, ofcourse, selected in accordance with the class ofbusiness transaction to be recorded. In the example referred to the twoaccounts which are influenced by the business transaction referred toare the cash account and the expense account.

When now the main shaft |00 is rocked in clockwise direction, the arm2|4 secured to the shaft is swung in the same direction, the pin 2|6 onsaid arm sliding in the slot 2|8 in the link 220 which thus is free tomove upwards permitting the double-armed levers |14 of the totalizersRA' and RC', which were released from their engagement with thecorresponding pawls |10, to swing in counter-clockwise direction underthe action of the springs |18 causing the totalizers RA' and RC to swingin the same direction through such an angle that the subtraction gears|56 of the totalizers come right above the corresponding transmissiongears |30,

stop bars |36 out of engagement with the actu-.

ator wheels, andthe actuator wheels 34 are free to turn `an anglecorresponding to ten teeth of the totalizer wheels. Thereby the actuatorrods i4 which correspond to keys that have'been actuated, are free tomove backwards, that is to say in the example referred to the actuatorrods i4 corresponding to the first, third, fth, eighth, ninth and tenthkey rows.

As already described the stopping plates i3 of the key rows G, H, K andL are so arranged in relation to the actuator rods I4 determining I thesetting of the actuator wheels 34 that said actuator wheels are alwaysrotated through one tooth even when the corresponding stopping plates i6have not been actuated, that is to say the actuator wheels correspondingto non-actuated key rows are turned one tooth and those corresponding toactuated key rowsare turned an additional tooth beyond the anglecorresponding to the position of the depressed key rod lll. As will bedescribed later this additional movement through one tooth is necessaryonly for the operation of the ten transfer means as shown in Figs. 4, 5and 6. that is to say only for the actuator rods of the numeral key rowsL but not for those of the key rows G, H, K, although the arrangementhas been adopted also for the last-mentioned key rows for the sake ofsymmetry.

ln agreement herewith and with the example referred to the actuatorwheels 34 appurtenant to depressed keys will be turned in the followingmanner reckoned from the left in Fig. 2: the rst gear one tooth(analysing key l), the third gear six teeth (month May), the fifth gearseven teeth (the day 6) and the eighth, ninth and tenth gears, eight,three and six teeth ($7.25),

Y respectively. Further rotation ofthe gears inuencing the analysing keyactuator wheel is prevented by the actuator rod I4 abutting against theabutment 53 on the releasing rod 50 of the key l. Also further rotationof those iniiuencing the other gears is prevented by the actuator rodsi4 abutting against the end of the keyrods l0 of the depressed keys. Allactuator wheels 34 corresponding to key rows which do not contain anydepressed key are turned one tooth, until the corresponding actuatorrods strike the locking plates i6. The actuator wheels which have beenactuated have, consequently, in order from the left in Fig. 2 been seton nl May, 6. 7, "2 and 5 andl the transmission gears |30 of said gearsare set in the same manner.

During the forward stroke of the'main shaft |00 thecounter 256, 260 forchronological nu-v meration has been moved forward. one step, so thatthe corresponding gears 34 and type rods 244 have been set on a numberone unit higher than the preceding number. For the sake of illustrationit may be assumed that the preceding number was 125 and the new number,consequently, 126.

On account of thepositive connection between 9 the actuator wheels 34 inthe three sections of the machine the setting of said wheels in thecentral'section C causes a corresponding setting of the wheels in thelateral sections A and B. By

means of the toothed sectors 234 and the linkages 238, 240 the settingof the actuator wheels 34 is transferred to the corresponding typecarriers 244 of the four printing devices TA, TB, TC and TD, and when inthe manner to be described the hammer mechanisms SA, SB, SC and SD arereleased at the end of the forward stroke or immediately before, thefollowing entry 126 1 May 6 7.25 will be printed in credit on the cashaccount card, in debit on the expense account card, on the voucher andon the day-list.

The release of the hammer mechanisms will be described with reference tothe mechanism SC as shown in Figs. 3 and 14.

At the end of the forward stroke of the driving shaft |00 roller 31| onarm 312 is turned into engagement with lever 353 rocking same inclockwise direction. This movement is transferred by the linkage 3GB-364to arm 363 which together with shaft 35| is rocked in counter-clockwisedirection. Thereby bridge 353 but the hammers 350 are still locked bypawls 356. After continued rotation of bridge 362 levers 313 are-alsoreleased. For all such type carriers 244 which have not been actuatedthis results in the levers 313 with their upper arms 313 being turnedbelow the corresponding pawls 353 under the action of springs 313, thelower arms 316 of the levers 313 engagingthe recesses 311 in the typecarriers 244. This results in the corresponding hammers 3,50 beinglocked. 0n

the contrary for such carriers 244 which correter-clockwise directioncausing the hammers to be released from their engagement by the pawls356. Such hammers 350 which are not locked by levers 313 are now whollyfree and turned by springs 354 in counter-clockwise direction strikingthe types 246 which are in printing position.

All the totalizers are still out oi engagement with the transmission RA"and RC 204e on the locking levers 234, totalizer TR on account of theconnection of its arm 211i with the arm 213 and all other totalizers bybeing supported by corresponding supporting bell-crank levers |64.Immediately before the end of the forward stroke of the main shaft |00the roller 196 on the arm |34 strikes the pawl i90, thus releasing theymember |84 with its arm |36 which swings downwards under the action ofthe spring 188, thereby swinging the levers 204 in clockwise direction.The totalizers supported by the supporting levers |64 remain unactuated,whereas the totalizers RA', RA" and RC" loose their supports and falldown and totalizer TR is swung into engagement with the transmissiongears 30. In the example referred to the subtraction gears |53 of thetotalizer RA'; the addition gears |52 of the totalizer RA", thesubtraction gears |56 of the totalizer RC' and the gears I268 of thetotalizer TR will thus be brought into engagement with the transmissiongears, 30, said transmission gears |30 having been set during the gears|33, totalizers RA',

362 releases all pawls by being supported by the pins setting of theselector. When now the main shaft with the arm M2 allows the crank liti]to carry out its return stroke under the fiction of the spring |06nothing occurs in the example referred to, before the arm i3d secured tothe actuator shaft 36 has been turned through an angle corresponding totwo teeth, the stop bars i3@ abutting then against a spoke |37 of thegear Sil corresponding to the ligure Tl which gear will then partake inthe following rotation. When the arm i313 turns further, through anangle equivalent to one tooth of the gear lfl, the gear 34 correspondingto date number is brought into position for engagement. After a furtherrotation equivalent to one tooth, the gear 3d corresponding to May andthat correspending to the figure 5 are brought into position forengagement. When three teeth remain. the gear corresponding to the gure2 will be brought into position for engagement. During this rotation thecorresponding gears in the totalizers RA, RA", RC and TR will be turnedthrough corresponding angles by the transmission gears i319. Thus, atthe end of the return stroke of the main shaft |00 $7.25 have beensubtracted from the amounts in the totalizers RA' and RC and added tothe amounts in the totalizers RA and TR.

Near the end of the return stroke the rollerl iSB on the arm ldabutsagainst the inclined `surface |98 on the projection 200 of the curvedmember |8 causing the link 202 to turn the levers 204 incounter-clockwise direction whereby the actuated totalizers RA', RA andRC are raised and the totalizer TR is swung out of engagement with thetransmission gears |30. Thereby the totalizers RA" and TR are returnedto normal positions, but the totalizers RA' and RC' are still insubtraction positions. They are returned to normal positions by the pin2|6 on the arm 2|4 abutting against the lower end of the slot 21s 'inthe uns 22u at the end of the return stroke, whereby the link 220 ismoved downwards swinging by means o the pins 230 the actuated levers H4of thetotalizers RA and RC set for subtraction in clockwise directioninto engagement with the pawls thus returning said totalizers intonormal position.

At the end o1 the return stroke the arm l5 (Fig. 3) secured to the mainshaft 00 is swung into engagement with the inclined surface 'l2 on thelever G0 turning said leve-r in clockwise direction whereby the end ofsaid lever engaging links 6d and d3 is lowered. The downward movement oflink @il causes the restoring plate Sil to be turned into engagementwith the abutment 5ft on the releasing bar 50 o-the actuated analysinglfzey l see Figs. 3 and 9), said bar being thereby lowered against theaction of spring 52 into engagement with the spring-actuated catch Ilwhich raises the key into normal position. The downward movement of link3 causes the restoring bar l5 to be moved to the right in Figs. 3 and 7causing the depressed keys in the key rows G, H, K and L to be raisedinto starting position under the action of the springs 23.

Now the machine is restored to normal position and a new businesstransaction can be immediately recorded.

Ten transfer in a totalizer is effected in the following manner (seeespeciallyFigs. 4, 5 and 6). The above said additional movement of theactuator rods i4 and additional rotation of the corresponding actuatorWheels through one tooth occurs at the end of the return stroke,

This rotation is transferred Aonly to the gears ll in mesh with-theactuator wheels but not to the wheels 130. This motion or" gear l3| lspermitted as said gear is capable of being turned one tooth independentof the gear |38 on account of the pin and slot connection |83, |85.Consequently, the correct setting of the actuator wheels 3ft determinedby the depression o the numeral keys is transferred to gears |30 but notthe additional tooth.

When during the return stroke of the machine the amount set up istransferred to the totalizer and a ten transfer is to take place, thatis to say when a totalizer wheel passes from nine to zero incounterclockwise direction as seen' in Figs. 3 and 4, the tooth |81 or|89 on such a Wheel presses down the arm |93 of the ten transfer paw]i533, |93 corresponding to said totalizer wheel. This causes the otherarm |91 of said pawl to move out of the path of the pin |83 of the gearl30 or the next higher order. During this rocking movement or the tentransfer pawl the pin |99 which was in engagement with the recess 20| inlever 205 is moved into the recess 203, spring 2|| locking the pawl inthis position.

When the actuator wheels are moved through the additional tooth at theend of the return stroke, this movement is'imparted to all of the gears13| but, for each order in which no tens transfer ls to take place, thegear |3i is locked against the additional tooth movement by theengagement of its pin |83 with the end of the tens transfer pawl |91 ofthe next lower order, and the spring is tensioned as the gear |30 movesa step further than the associated gear |30. In those transmission gearsin which a tens transfer is to take place the arm |91 of the tentransfer pawl of they next lower order has been rocked out of the pathof pin |83 and the gear |30 partakes in the rotation of its associatedgear i3| through the addition step or one-tooth displacement, thuseffecting a tens transfer to the associated totalizer wheel.Consequently, at the end of the return stroke of the machine, gears |30,|3| in which ten transfer has taken place are not in starting position.The restoring of said gears into starting position is elfected at thebeginning of the next machine stroke ln the following mann-er.

:immediately atthe beginning of the rotation of the driving shai't lol)during the next machine stroke arm 2.2i rocks catch in counter-clockwisedirection (see Fig. l0) causing lever i222" to be rocked in the samedirection. Thereby lint:

2.3i is moved downwardly rocking bell-crank lever 39 in clockwisedirection. This movement transferred by link 2&3 and arm to shaft itlwhich is rocked in clockwise direction as seen ln Figs. 3 and 4 and incounter-clockwise direction as seen in Fig. 5. Thereby the curved end ofrestoring arm 2|3 secured to said shaft |9| presses down pin |83 andsimultaneously rod 2 releases locking lever 205 which by means of spring2li rocks the ten transfer pawl |93, |91 in counterclockwise directionas seen in Fig. 4 and in clockwise direction as seen in Fig. 5 causingpin |59 on said paw] to move from recess 203 into recess 20| and' arm|31 of the pawl to lock pin |83. Now all transmission gears |30, |3| aswell as all other ten transfer members are restored to startingposition.

Fig. 15 illustrates how a ten transfer mechanism of conventional typedisclosed in the Burroughs Patent No. 594,963 can easily be applied tothe present machine. Parts in this figure and be released which arminfluenced intermediary of shoulder 392. By

-, trolled by the gear |52 in Figs. 4, and 6 vwhich have the samefobiect and operation are designated by the 'same reference numerals.

The transmission gears |30 and |3| are shaped as sectors connected witheach other by the spring and by the pin and slot connection |83, |85 asin the' previous embodiment. Here the arms |93 and 91 of the tentransfer pawl are formed as separate parts and pivoted on shaft |9|. Theprojection 25| on arm |93 cooperates with a recess in a. stop member 390on locking lever 205 fulcrumed at 209. Spring 2|| tends to keep stopmember 390 into engagement with the projection Arm |91 is influenced bya spring 39| which tends to keep the arm in engagement with a shoulder392 on lever 205. Another spring 393 tends to keep arm |93 in raisedposition. A rod 394 engages recesses in the arms |93 and |91 to controlthe movements thereof. Arms 2|5 supporting between them the returningrod 2|1 is fixed to shaft 209 instead of shaft |9| as in the previousembodiment. The

mechanism for returning the ten transfer mech-V anism to initialposition is the same as in the previous embodiment except that arm 245is fixed to shaft 209 instead of to shaft |9|.

When the totalizer wheels pass from nine to zero, the tooth |81 or |89will abut against the trip |95 to rock the transfer arm |93. Thereby theprojection 25| will be disengaged from stop member 390 which causeslocking lever 205 tc by spring 2| |v slides along the projection 25| andmoves arm |91 from engagement with pin |83 through the this means thetooth sector is allowed to move one additional step, whereby the tentransfer is performed.

When at the beginning of the forward stroke link 231 is drawn downwardlyas described above, this movement is transferred by bell-crank lever 239and link 2.43 to. arm 245 which is rocked in counter-clockwise directiontogether with arms 2|5. Thereby the returning rod 2l1 rocks lever 205 incounter-clockwise direction. When during this movement. stop member 390slides from the Aextreme point of projection 25| on the transf er arm|93 this arm |93 is raised by spring 393, so that the projection 25| cansnap into the recess in the stop member 390. Arm |91 is returned to itsinitial position by means of spring 39| upon the gear |3| having beenturned one tooth and the pin |83 has moved past the lever, which iseected during the next forward stroke when the transmissiongear |3| isset by the actuator' wheel 34.

Figs. 16, 17 and 18 .illustrate how a ten .trans-V fer mechanism ofanother conventional type disclosed in Patent No. 1,853,053 can beeasily ap plied t'o the present machine. l

This transfer mechanism includes a plurality of toothed -transfersegments 400 pivoted on a shaft 40| carried by side plates 402 (see Fig.17),

there being one transfer segment for each pair of toothed gears |52,|56. The transfer segment 400 is normally held in the position shown inFig. 16 by the engagement of a lateral lug 402 on an arm 403 of thesegment in a notch 404in a bell-crank detent 405 which is pivoted on ashaft 406 and urged in clockwise direction by the I spring 401. Thebell-crank detent 405 is conof next lower order than the one with whichthe transfer segment engages. An arm 408 of the detent 405 extends abovea pivoted tripping pawl 4|0 having a tooth-like projection 4|| adaptedto be engaged by a broad 1 1 tooth 4 |2on` the gear |52. The trippingpawl 4|0 is pivoted'on a shaft 4|4 carried by the frame bridges |60 ofthe totalizer so that the pawl moves with the totalizer as it is movedinto and out of engagement with the transmission gears |30, and it isurged in a counter-clockwise direction by a spring 4|5, one end-of whichis .connected to the tail of the pawl and the other end of which isconnected to a latch 4|6 pivoted on the spindle |58. A lateralprojection 420 is formed on the pawl 4|0 forengagement with'a shoulder42| on the latch r4|6 which latches the pawl in raised position undercertain conditions hereinafter explained.

For the purpose of carrying when the totalizer is performing .additionthe transfer segments 400 are normally urged in a clockwise direction bysprings 422 connected at one end to the arms 403 of the segments and attheir other ends to a rod 423 carried by a cross bar 424 of a bail 425pivoted as at 426.

A restoring bail for the segments is provided comprising a cross shaft428 carried by arms 430 (see Fig. 17) pivoted on a rocking yoke 43|, 432as at 433, said yoke being -fixed to a rock shaft 434 pivoteddn the sidearms 402. This bail moves in slots 435 in the side plates 402 andbetween the extending arms 436 of the transfer segment from the positionbetween the narrow opening between said arms to the wider openingbetween them. As it moves to the right it engages the upper arm 436 ofthe segment and cams it counter-clockwise to normal position, the partsbeing proportioned so that the segment is moved su'iciently to ensurethat the detent 405will catch on the lug 402.

When one of the gears |52 is rotated from its 9 position to its 0position the wide tooth 4|2 lon the gear engages the projection 4|| onthe tripping pawl 4|0 and cams it upwardly to a position in which thepawl is latched in place by the latch 4|\6 which moves the shoulder 42|beneath the lug 420. When the totalizer is moved upwardly out ofengagement with the transmission gears |30 it carries the tripping pawl405 with it and the upper side of the pawl, engaging the arm 408, movesthe detent 405 counter-clockwise and releases the transfer segand 17 inthe wide space between the arms 436 Y of the transfer segment whichpermits the segment to turn on its pivot 40| without interference fromthe restoring bail. The bail 428 acts as a. limit stop for the segmentto limit its movement to an amount just sufficient to move its gear onetooth.` As the bail moves to the left, it contacts the ends of all thelatches 4|6 and swings them out of engagement with the lugs 420 on thetripping pawls 405, whereupon these pawls arel restored to normalposition by the springs 4|5.

The transfer mechanism is restored to normal when the totalizer is nextmoved into engagement withvthe transmission gears |30. As this movementoccurs the bail 428 is moved to the right in Fig. 16 and it .engages theupper arms
